GEORGE E. OHAMBERLAIN, 0F ST. Lotus,H MISSOURI. SHAFT-HANGER.

T0 all whom it may concern:

Be it known that I, GEORGE E. CHAMBER- LAIN, a citizen of the United States, and a resident of the city of St. Louis and State of Missouri, have invented a new and useful lmprovement in Shaft-Hangers, of which the following is a specification.

It is a common fault with shaft-hangers in general use for supporting. screw-conveys;` shafts that their fastening nuts or bolts orl other arts work loose in practice and fall into t e conveyer-trough. The parts that thus get into the conve ver-trough are carried along with the materia and often cause serious accidents to the machinery' that the Inaterial is fed to.

It is the principal object ofv my invention to avoid the dan er of parts of thehanger gettino` into the fee -trough.

nother important object is to provide for the easy removal of the conveyer-shaft without loosening the shaft-hanger.

Another important object is to avoid the obstruction of the conveyer-trough as far as practicable.

My invention consists inthe parts and arrangements and combinations of parts hereinafter described and claimed.

In the laccompanying drawings, Whieh form part of this specification, and wherein like symbols refer to like parts wherever they occur, Figure 1 is a vertical view of my hanger, pprtly in elevation and partly in section, loo 'ng endwise of the shaft. Fig. 2 is a side elevation of my. hanger. Fig. 3 is a vertical cross-section thereof. Fig. 4 is a horizontal section on the line f1 4 of Fig, 1. Fig. 5 is a horizontal section on .the line 5 5 of Fig. 1, and Fig. 6 is a cross-section through a conveyer-trough, showing the hanger inposition.

Myshaft-hanger comprises a yoke 1, whose arms are provided with lateral extensions 2 at their upper ends. These lateral extensions are adapted to rest upon the side walls of the conveyertrough and are provided with downturned flanges 3, overhangi ng said walls. They may also be secured to the walls` of the trough by any other suitable means. The lower portion of the yoke is of less width than the upper portion, and this lower portion is preferab y rounded at the corners, so as to cause as little obstruction as racticable in the trough. The inner face o the narrower lower portion of the yoke is provided witha groove, and in this groove lit ribs 4, provided specification of Letters Patent'.

Application filed lvaylg, 1905. Serial No. 261.162.

and stren th to the han er.

for the purposeon the separable members 6 of the journal-bearing. The `journal-bearing l, katentedmaygg, .i

is of any suitable type and provided with the usual lining. y Resting on t eupper member of the journal-bearing is a heavy block 7,

Whose under vside is; grooved'to iit over the rib on the top surface-of` the upper member of :the journalbearing; f Obviously the block y and the upper member might Ibemade of one piece..

At the to of the yoke,`on the inner faces thereof, are u s 9 10, through which vertical screw-threads holes extend. Th( faces of these lugs are beveled, and over t eir beveled `surfaces rest the counterbored portions of a cover-plate 13, which has holes arranged in alinement with the lug-holes. Threaded bolts extend through vthe coverplate and the threaded lug-holes downwardly against the top surface o per portion of the yoke 1 being grooved to accommodate saidbolts. These bolts are provided with set-nuts 14 15, which bear against the coverlate. An oil-tube 16 also extends downward y through the cover-plate and through the block and the upper member of' the journal-bearing.

In practice the shaft-hanger is mounted on the side walls of the conveyer-trough and secured firmly in place by any suitable means. When it is desired to remove a section of the conve er-shaft, it is not necessary to unfasten tliie shaft-hanger from t/he conveyertrough. In such case the bolts are unscrewed from the lugs without removing the set-nuts from the bolts. Then the coverplate and the block and the upper member of the journal-bearing are removed and the shaft-section lifted out.

It is to be noted that the interlocking of the cover-plate with the'yoke gives great rigidity It is also noted that the oosening of t e bolts is not only guarded against, but that such loosening cannot result 1n the accidental falling of the bolts or other arts into the conveyer-trough.

What claim as my invention, and desire to secure by Letters Patent, is-

. 1. A shaft-hanger comprising a depending yoke having substantially parallel branches provided with grooves on their inner sides, sai'd yoke having lateralv extensions on the outer sides of its branches and lugs on the inner sides of its branches provided with threaded holes ahmed-with said grooves, a.

journal-bearing removably/ arranged in the u per 75 the block, the up- IOC 5 yoke, a bearing mounted in the lower portion of said yoke, the upper portion of said yoke being open, a cover-plate closing said yoke at the top, 'and screws securing said cover-plate to said yoke and engaging said bearing and ro securing the same in position.

A shafthanger comprising a depending yoke having branches separated from each other at the top and having lugs on the inner faces of the upper ends of said branches pro- 15 vided with tapped holes, a cover-plate connecting the u )per ends of said branches and provided wit holes in alinement with said tapped holes, a bearing removably mounted in the lower portion of said yoke, and screws passing through said holes in said cover-plate and said lugs and engaging said bearing. f 4. A shaft-hanger comprising a depending yoke having substantially parallel branches separated from eachother at the top and provided with grooves on the inner sides between their ends and lugs at their upper ends provided with tapped holes alined with said grooves, a cover-plate connecting the upper ends of said branches and having holes in alinernent with said tapped holes, abearing removably mounted in the lower portion of said yoke, and screws passing through said holes inssaid cover-plate and said lugs, lying in said grooves and engaging said bearing.
